Description
Music Speed Changer allows you to change the speed of audio files on your device in real time without affecting the pitch (time stretch), or change the pitch without changing the speed (pitch shift). Alternatively, both speed and pitch may be adjusted together with a single control. The app is a music looper as well - you can slow down song speed and loop sections of the music for easy practice.
You can also save the adjusted audio to an MP3, FLAC, or WAV audio file for sharing with friends or listening in another player.
Music Speed Changer is great for musicians practicing an instrument needing to slow down the tempo or practice in a different tuning, speeding up audio books for faster listening, making nightcore or just rocking out to your favorite song at 130%.

I LOVE this app. And I mean LOVE it. I love how you can change the Hz frequency ranging to a literal octave! And the speed is very flexible too! This is the first app that I've found to fulfill my needs for when I need to listen to classical music. Its name tells you that it can change its speed (main core), but it includes much more than I thought. Thank you very much to the creators of this app. Keep it up!

Very amazing app, able to reduce speed without changing pitch! Able to split tracks of any song. Beautiful! I recommend it! Maybe, help and perfect the pitch maintenance on reduce the song's tempo

Fun and works as described. Have had it on my Motorola for a long time and is the one "music speed changer" app that I didn't uninstall. Plus it has other useful features that aren't gimmicky.

It won't OPEN ANY FILES!! It won't EXPLAIN HOW TO DO THAT!! No one on YouTube is seen uploading A SONG TO THE APP!! "File will not open" is not helping. Why not open? Where do you want the file from?
